WARRENVILLE, Ill.--(BUSINESS WIRE)--Fuel Tech, Inc. (NASDAQ: FTEK), a technology company providing
advanced engineering solutions for the optimization of combustion
systems, emissions control and water treatment in utility and industrial
applications, today reported financial results for the fourth quarter
(“Q4 2018”) and full year ended December 31, 2018.

“We ended 2018 with two of the strongest quarters in recent history,”
said Vincent J. Arnone, Chairman, President, and CEO of Fuel Tech. “In
Q4 2018, specifically, revenues rose at our Air Pollution Control
(“APC”) and FUEL CHEM® segments, SG&A declined on a quarterly
comparative basis for the fourth consecutive quarter, and we generated
operating income from continuing operations of $0.9 million. For all of
2018, revenues increased by 25.2%, SG&A declined by 11.3% and we
reported our first annual operating profit since 2013. We ended the year
with over $18.0 million in total cash and are debt free.

“Our consolidated financial performance in 2018 included the negative
impact of our China operations (“Beijing Fuel Tech”). For the full year
of 2018, Beijing Fuel Tech generated an operating loss of $1.9 million
and revenues of just $3.0 million. As previously announced, we have
commenced the process of suspending our operations in China and expect
that this will be substantially completed by the end of Q2 2019. As we
complete our planned suspension activities in 2019, the negative impact
of Beijing Fuel Tech’s operating losses on Fuel Tech’s overall
performance will dissipate.”

He continued, “Our APC solutions portfolio continued to demonstrate
flexibility and adaptability with respect to fuel source. In 2018,
approximately 60% of total APC revenue was derived from natural gas
applications, up from 21% in 2017 and 4% in 2016. Our ability to apply
our technology suite to natural gas-fired applications is critical for
our Company, as the fuel mix for new power generation sources has
shifted dramatically in favor of natural gas and away from other fossil
fuels. For our FUEL CHEM business, which predominantly assists
coal-fired power generation in their effort to burn lower-quality fuels
more cleanly and efficiently, we had a nice improvement in revenue
generation in 2018 versus 2017. Coal as a fuel source for power
generation is likely to be a part of the fuel mix in the U.S. for many
years to come, and we expect to maintain a consistent level of revenue
contribution from this business segment in the near-term.

“We continue to progress in developing our new water treatment business.
We are in discussions with multiple potential customers and we target to
have a demonstration up-and-running by early Q2 2019. We now have a
mobile demonstration-scale system ready to be deployed and can respond
rapidly to a customer request. While we do not expect our water
treatment technology venture to have a significant impact on near-term
results, we do look forward to it being a significant contributor in
future years.”

Mr. Arnone concluded, “We have successfully emerged from executing on a
multi-year program of cost reduction and rationalization initiatives.
The completion of the suspension of our China operation in 2019 will
enable improved profitability for the Company as a whole, and for full
year 2019 we expect to generate both income from continuing operations
and positive cash flow for the second consecutive year. Further business
development for our APC and FUEL CHEM business segments remains as
priority. We are currently pursuing a pipeline of opportunities with an
aggregate value of greater than $100 million that covers all fuel
sources, involves the application of the entirety of our product line
and serves customers in multiple geographies. We are also looking
forward to our first commercial efforts in water treatment.”

Q4 2018 Results Overview

Consolidated revenues rose 18.2% to $15.8 million from $13.4 million in
Q4 2017, reflecting higher revenues at APC and FUEL CHEM.

Gross margin declined to 37.3% of revenues from 42.0% in Q4 2017, due to
the mix between APC and FUEL CHEM revenues recognized during the
quarter. With an increase in APC revenues in Q4 2018 as compared to Q4
2017, the overall weighted average margin on a consolidated basis
declined.

SG&A expenses declined to $4.8 million, or 30.2% of revenues, from $4.9
million, or 36.5% of revenues, in Q4 2017.

Net income from continuing operations was $0.9 million, or $0.04 per
diluted share, compared to net income from continuing operations of $1.0
million, or $0.04 per diluted share, in Q4 2017. Results for Q4 2017
were revised to include an income tax benefit of $0.6 million reflecting
a deferred tax liability associated with the historical goodwill of FUEL
CHEM.

Net income was $0.9 million, or $0.04 per diluted share, as compared to
a net loss of $(0.7) million, or $(0.03) per diluted share, in Q4 2017.

Results for Q4 2018 included revenues of $0.6 million from Beijing Fuel
Tech as compared to $1.6 million in Q4 2017, and operating losses of
$0.4 million for both Q4 2018 and Q4 2017.

APC segment revenues rose by 11.4% to $10.5 million from $9.5 million in
Q4 2017, driven by the conversion of new orders. APC gross margin was
$3.2 million, or 30.4%, as compared to $3.8 million, or 39.9%, in Q4
2017. The decline in gross margin in Q4 2018 was due to product line and
geographical mix as compared to the prior year’s quarter.

FUEL CHEM segment revenues rose 34.6% to $5.3 million from $3.9 million
in Q4 2017, reflecting favorable weather conditions and the addition of
a new coal-fired unit at an existing customer in the midwestern US
during Q3 2018. Segment gross margin was 51.1% in Q4 2018 and 47.2% in
Q4 2017.

Research and development expenses for Q4 2018 and Q4 2017 were $0.3
million.

Capital projects backlog at December 31, 2018 was $12.4 million, $11.0
million of which was domestic.

Adjusted EBITDA for Q4 2018 rose to $1.2 million from Adjusted EBITDA of
$0.6 million in Q4 2017.

2018 Annual Results

Consolidated revenues for 2018 rose 25.2% to $56.5 million from $45.2
million in 2017, due primarily to the reasons cited above.

Gross margin declined to 35.5% of revenues from 39.9% in 2017, due to
the mix between APC and FUEL CHEM revenues recognized during the year.

SG&A expenses for the year declined 11.3% to $18.6 million from $20.9
million in 2017. On a total dollar basis, SG&A for the year decreased by
$2.4 million.

Adjusted EBITDA

To supplement the Company's consolidated financial statements presented
in accordance with generally accepted accounting principles in the
United States (GAAP), the Company has provided an Adjusted EBITDA
disclosure as a measure of financial performance. Adjusted EBITDA is
defined as net income (loss) before interest expense, income tax expense
(benefit), depreciation expense, amortization expense, stock
compensation expense, and intangible assets abandonment and building
impairment. The Company's reference to these non-GAAP measures should be
considered in addition to results prepared in accordance with GAAP
standards, but are not a substitute for, or superior to, GAAP results.

Adjusted EBITDA is provided to enhance investors' overall understanding
of the Company's current financial performance and ability to generate
cash flow, which we believe is a meaningful measure for our investor and
analyst communities. In many cases non-GAAP financial measures are
utilized by these individuals to evaluate Company performance and
ultimately determine a reasonable valuation for our common stock. A
reconciliation of Adjusted EBITDA to the nearest GAAP measure of net
income (loss) has been included in the above financial table.
